SurtlingFuelItemHopperFix

SurtlingFuel ItemHopper Fix

Lets ItemHopper feed Surtling Cores, Black Cores and configured core-like items into vanilla smelters and blast furnaces, using SurtlingFuel's fuel amount and speed boost.

What it does

• Keeps coal and core fuel separate: one waits until the other is spent.
• Leaves items in the source when the machine is full or rejects the fuel locally.
• Restricts core fuel to smelter and blastfurnace; Eitr Refineries and other

machines do not receive core fuel or its speed boost.

• Repairs SurtlingFuel 1.4.0's older Valheim API calls.
• Protects honey and dropped-item transfers when insertion or pickup fails.
• Preserves item provenance when a dropped item merges into an existing stack.

Version 1.2.2 fixes that last case. A successful pickup of an item marked as cheated now keeps that flag on the receiving stack. A refused pickup leaves the destination's previous count and flag unchanged.

Install

Install this package and all dependencies on the server and every client, using Thunderstore Mod Manager or r2modman. For a downloaded ZIP, use Import local mod. Everyone must use the same add-on version, then restart.

For manual installation, put SurtlingFuelItemHopperFix.dll in BepInEx/plugins/SurtlingFuelItemHopperFix/ and install dependencies separately.

Current dependency baseline

| Dependency | Version | |---|---| | Valheim | 1.0.16 | | BepInExPack Valheim | 5.4.2351 | | Jötunn | 2.30.2 | | ItemHopper | 2.0.2 | | SurtlingFuel | 1.4.0 | | MultiUserChest, required by ItemHopper | 0.6.2 |

Keep both ItemHopper and SurtlingFuel installed. This package is their compatibility add-on and contains neither dependency.

Settings

After the first launch, edit BepInEx/config/local.valheim.surtlingfuelitemhopperfix.cfg:

| Setting | Default | Effect | |---|---|---| | Fuel / Additional Fuel Prefabs | BlackCore | Extra internal item prefab names accepted as core fuel by hoppers. |

Separate names with commas, semicolons or new lines. SurtlingCore is always enabled; Coal is excluded from this list. The list is synced from the server and controlled by its admins.

Every listed extra item receives the same fuel value and speed boost as a Surtling Core. Remove BlackCore from the list if hoppers should not consume Black Cores. This setting does not add manual Black Core fueling.

SurtlingFuel's own fuel-per-core and speed settings remain in its config. Keep those values identical on the server and clients; SurtlingFuel 1.4.0 does not synchronize them itself.

Limits and removal

Fuel and ore delivery retain ItemHopper's remove-then-RPC network protocol. This release does not add transaction acknowledgements; simultaneous remote transfers or disconnects during delivery are not guaranteed by the local-owner checks. Other mods that replace these same methods may conflict.

Removing this package restores upstream behavior and removes these compatibility guards. It adds no items or recipes. Existing fuel stored by SurtlingFuel remains part of that mod's state.
